Tips for Choosing the Right Dust Collector

Tips for Choosing the Right Dust Collector

Not everyone is a dust collection expert. Lack of knowledge can lead to some unpleasant surprises for potential buyers who believe that a supplier-recommended capture system is always the informed result of an assessment that has taken the specifics of their procedures into consideration.

It is important to understand that there are no ‘wrong’ types of dust collector. However, each model has its strengths and weaknesses. The choice of a particular model is based on various criteria that are specific to the company’s needs.

In this newsletter, we will try to provide a simplified overview of the features of the three main models found on the market.

The Shaker Dust Collector

The Shaker Dust Collector

Manual or motorized shaker units are based on proven older technologies. However, they are not the way to go when looking for a continuous, high-performing option for industrial use.

Details:

  • Long, mandatory periodic stops to clean the filter bags.
  • To minimize downtime, it is preferable to operate the dust collector at a low air-to-cloth ratio (related to the type of filtered contaminant) .
  • Ideal for occasional or alternating use, such as in mid-sized cabinet making shops and vocational schools.

The Cyclonic Dust Collector

The Cyclonic Dust Collector

For this unit to be effective, it requires a significant quantity of larger particles. This type of dust collector uses the cyclonic effect to separate larger particles and subsequently capture fine particles using filter bags.

Details:

  • Design requires a higher space.
  • The need to maintain the cyclonic effect and the resulting high static pressure results in high energy consumption.
  • Self-cleaning filter bag system allows for continuous use.

The Rectangular Dust Collector

The Rectangular Dust Collector

This model offers a myriad of customizable options to adapt to the client's needs. This model is among the most effective based on filtering capacity versus energy required for proper operation of the unit.

Details:

  • Self-cleaning filter bag system allows for continuous use.
  • Low loss of pressure results from high-performing, low energy blower.
  • Design requires less height.

Conclusion

The purpose of this summary is not to make you an expert in dust collection or encourage you to design your next unit on your own. It is, rather, to give you the tools to become an informed buyer so that you can be critical of proposals from your supplier.
